90 = XC
90
Depends on what you are wanting to figure. Here are a couple samples:Tons to CWT - 90 Tons = 1800 CWT to figure this you do the calculation of 90 * 20 (This is the shortcut)the long route is 90/100 = .9 then .9 * 2000 = 1800 (2000 lbs in a Ton)
Both a square and a rectangle have 4 angles of 90 degrees.
90
The digit 90 has only one applicable significant figure.
119.7, couldn't figure that out yourself? 90 x .133 = 119.7
Take any one point on the figure. Draw a line from it to the origin. At the origin measure an angle of 90 degrees (right angle) in a clockwise direction. Draw a line from the origin at this new angle and of the same length as the original angle. Repeat this process for the other points in the figure. NB Be careful, there will be numerous lines from the origin. At the end points of the new lines, connect up to reveal the origin figure ,but rotated 90 degrees - clockwise.
A square is a four-sided figure with four 90-degree angles.
75% of 90 = 75% * 90 = 0.75 * 90 = 67.5
Before that instruction, the problem gave you two numbers, and one numberis SMALLER than the other one.Now, the problem wants you to take the smaller one, figure out what 3 times itis, and then either increase that by 90 or multiply that by 90.
a right angle which is 90 degrees
